When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application.
On intelligent electronic equipment such as a mobile phone and a tablet computer, due to the need of integrating a photosensitive device such as a front camera and a light sensor, the inventor researches and discovers that full-screen display of the electronic equipment can be realized by arranging a transparent display screen on the electronic equipment.

Referring to fig. 1, the display substrate 100 includes a first display region 10 and a second display region 20, a light transmittance of the first display region 10 is greater than a light transmittance of the second display region 20, and the display substrate 100 includes a substrate 1, a first electrode layer 2 on the substrate 1, a light emitting structure layer 3 on the first electrode layer 2, and a second electrode layer 4 on the light emitting structure layer 3.
Referring to fig. 4 to 8, the first electrode layer 2 in the first display region 10 includes a plurality of first electrode groups 21 arranged along a first direction, each first electrode group 21 includes a plurality of first electrodes 211, the first electrodes 211 in the same first electrode group 21 extend along a second direction, and the second direction intersects with the first direction; each first electrode 211 comprises one first electrode block 2111 or a plurality of first electrode blocks 2111, and when the first electrode 211 comprises a plurality of first electrode blocks 2111, two adjacent first electrode blocks 2111 are electrically connected.
Referring to fig. 2 and 3, the first display region 10 includes a plurality of sub-display regions 101, at least one edge of each sub-display region 101 is adjacent to the second display region 20; referring again to fig. 4 to 8, each first electrode 211 is disposed in only one sub-display region 101, and different first electrodes 211 are driven by different pixel circuits.
The display substrate 100 provided in the embodiment of the present application is located in the plurality of first electrodes 211 included in the first electrode layer 2 of the first display region 10, each first electrode 211 is disposed in only one sub-display region 101, and different first electrodes 211 are driven by different pixel circuits, the sub-pixels corresponding to the first electrodes 211 in each sub-display region 101 can be controlled individually, further, the input voltage of the data line of the pixel circuit corresponding to the first electrode 211 in the sub display region 101 can be controlled according to the brightness of the region of the second display region 20 adjacent to the sub display region 101, therefore, the display brightness of each sub-display area 101 can be independently adjusted, so that the display brightness of each sub-display area 101 is close to the brightness of the adjacent second display area 20, thereby avoiding a large difference between the display brightness of the first display area 10 and the display brightness of the second display area 20, and improving the use experience of users.
A plurality of pixel circuits for driving the sub-pixels in the first display region and the second display region are disposed in the display substrate 100. Different first electrodes 211 are driven by different pixel circuits, where "different" means "not the same", that is, there is no case where two first electrodes 211 are driven by one pixel circuit, for example, two first electrodes 211 correspond to two pixel circuits one to one, and one first electrode 211 is driven by one pixel circuit; alternatively, the two first electrodes 211 are driven by three pixel circuits, wherein one first electrode 211 is driven by one of the pixel circuits, and the other first electrode 211 is driven by the other two pixel circuits.

With such an arrangement, the luminance of each sub-display area 101 of the first display area 10 is relatively close to the luminance of the area of the second display area 20 adjacent to the sub-display area 101, so as to reduce the luminance difference between the first display area 10 and the second display area 20.

Generally, the first display region 10 includes two or three sub-display regions 101.
